Abstract

Numerous metropolises worldwide have adopted transit-oriented development (TOD) as a sustainable urban development tactic. And the node-place model is the most commonly used model for TOD typology. However, the spatial vitality, one of the most fundamental aspects of TOD, has not been systematically taken into account in the node-place model. Therefore, this article introduces vitality as a third dimension into node-place model and develops the node-place-vitality (NPV) model, aiming to comprehensively re-classify and re-evaluate TOD performance. The independent weight coefficient method is used to compute place values, node values, vitality values, and overall TOD degree. Moreover, the categorization of TOD typologies makes use of the K-means++ clustering approach. The model is employed in a case study in Wuhan, China. The results show that the TOD degree exhibits a spatial discrepancy, characterized as “high-medium-low” from the center to the periphery, not only in the whole city but also in the three towns. The geographical characteristics of TOD degree within station catchment area are revealed by the heat map. Five TOD types are identified and they present obvious spatial differentiation. The approach proposed in this paper furnishes urban planners and decision-makers with a scientific instrument for assisting TOD planning and strategies designing.

结合空间活力和节点-地点模型对武汉地铁站区进行评估和分类

世界上许多大都市都将公交导向开发（TOD）作为一种可持续的城市发展策略。而节点-地点模型是最常用的 TOD 类型模型。然而，作为 TOD 最基本的内容之一，空间活力在节点-地点模型中并没有得到系统的考虑。因此，本文将活力作为第三个维度引入节点-地点模型，并建立了节点-地点-活力（NPV）模型，旨在对 TOD 的绩效进行全面的再分类和再评价。采用独立权重系数法计算地点值、节点值、活力值和总体 TOD 程度。此外，TOD 类型的分类采用了 K-means++ 聚类方法。该模型在中国武汉的一项案例研究中得到了应用。结果表明，不仅在整个城市，而且在三个城镇，TOD 的程度都呈现出从中心到边缘的 "高-中-低 "的空间差异。热力图揭示了车站集水区内 TOD 程度的地理特征。本文确定了五种 TOD 类型，它们呈现出明显的空间差异。本文提出的方法为城市规划者和决策者提供了辅助 TOD 规划和战略设计的科学工具。

期刊介绍： Frontiers of Architectural Research is an international journal that publishes original research papers, review articles, and case studies to promote rapid communication and exchange among scholars, architects, and engineers. This journal introduces and reviews significant and pioneering achievements in the field of architecture research. Subject areas include the primary branches of architecture, such as architectural design and theory, architectural science and technology, urban planning, landscaping architecture, existing building renovation, and architectural heritage conservation. The journal encourages studies based on a rigorous scientific approach and state-of-the-art technology. All published papers reflect original research works and basic theories, models, computing, and design in architecture. High-quality papers addressing the social aspects of architecture are also welcome. This journal is strictly peer-reviewed and accepts only original manuscripts submitted in English.
